Macrosoma costilunata is species of moth-like butterfly in the family Hedylidae.[1] It was first described by Louis Beethoven Prout in 1916 and originally classified in the genus Phellinodes.[2]
Distribution
[edit]The species is found in north-western Costa Rica and northern and central Ecuador.[2][3]

[edit]Wings
[edit]The wings are grayish brown ground color. Forewing is weakly emarginate with dark brown apex. The costa is postmedial with lunate off-white patch. Three small white marks can be found near the apex.
The length of the forewing is 21–22 mm.[3]
Genitalia
[edit]Male
[edit]Following are the characteristics of the male genitalia:[3]
- Saccus is very short.
- Uncus is apically pointed and is not extending to apex of valva.
- The central element of Gnathos is spinose, downcurved and the lateral components denticulate.
- Valva is narrow, subtriangular and the apex neither upcurved nor upturned.
Female
[edit]The female genitalia has the following features:[3]
- Anal papillae is rounded at apices.
- Signum is denticulate.
